Claims. (01. 18421) My invention relates to a greasing device for to pass around the rail 6 and in close relation tracks, and more particularly to a device for unithereto. formly greasing the guide-rails of elevators. Resilient side flaps l are hingedly connected, An object of this invention is to provide a greasone to each of the side walls 2, and adapted to 5. ing device which may be carried by an elevator, normally swing inwardly between the upper and 5 and which will evenly distribute grease on the lower walls 3 and I respectively and against the face and sides of the elevator rails during the side of the rail 6, as shown in Fig. 3.

A block I2 is slidably disposed in the box-like 4.5 In order to facilitate ease of refilling the box-like structure of the device and formed to press against structure, the door or lid 4 when opened is of the grease placed therein. One end of an arm l3 sufiicient size to expose the whole of the contents is pivotally connected to the block l2 and the of said device. other end of the arm is pivotally connected to the One end of the box-like housing is provided with lower end of the swinging rod M.

This slot 5 is formed able weight IS. The weight [6 may consist of a 55 plurality of disks which are carried upon the upper end of a bar IT. The lower end of the bar I1 is rigidly secured to the bar l4 and projected at a slight angle upwardly therefrom. A collar !8 is movably supported upon the upper end of the bar l1 and serves as a base for the disks to rest upon. The disks may be provided with slots or central openings for placing them on the bar l1 and upon the collar l8. When the pressure on the grease is to be varied, the number of disks is either increased or decreased.

The rear wall II is provided with a slot IQ for the passage of the arm l3, and the arm I3 is curved to permit the same to function with the swing of the rod Hi.

When a stick of grease is inserted through the door or lid 4 into the box-like structure of the device, the block I2 is moved so that its pressure will be exerted against the end of the grease stick opposite the end which contacts with the rail 6. As the grease is applied to the rail, the weight l6 will continue to press the grease stick forward until the grease is completely distributed upon the rail.

What I claim is:

1. In a greasing device for rails consisting of a box-like'body having slots in the forward end adapted to receive a guide rail, resilient flaps resiliently connected to said body and adapted to normally bear against the sides of said rail for directing grease thereto, a follower block slidably carried in said body for feeding grease toward said rail, and means carried by said body and cooperating with said block for forcing said grease toward the guide rail.

2. In a greasing device for guide rails conto contain grease, means for exerting pressure upon said grease, said body having slots adapted to receive said rail, and resilient flaps carried on said body and adapted to crowd said grease toward said rail.

3. In a greasing device for guide rails consisting of an elongated body adapted to contain grease, one end of said body being slotted to receive said rail, flaps hingedly carried on said body and adapted to project inwardly at an angle to said rail so that the edges opposite their hinges will bear against the sides of said rails and crowd said grease thereto, and means for exerting pressure on said grease for forcing it against said rail.

4. In a greasing device for guide rails consisting of a box-like grease-containing body adapted to be carried by the vehicle upon said rail, one end of said body being slotted to receive said rail, flaps hingedly carried on said body and adapted to normally resiliently crowd said grease toward the sides of said rail, said flaps being provided with grooves adapted to wedge said grease between said rail and said grooves, during the travel of said vehicle, a weight means carried by said body for exerting pressure upon said grease for forcing the same against said rail and between said flaps.

5. In a greasing device for rails consisting of a grease holding body having slots for receiving said rail, resilient flaps carried by said body and adapted to direct said grease against the sides of said rail, said flaps being provided with grooves for guiding and wedging said grease against said rail, and a weight suspended on said body and adapted to force said grease between said flaps and against said rail.
